Cerium tungsten bronzes, Cex, WO3 were prepared by the high temperature, solid state reaction of CeO2, W, and WO3. The intimately mixed reactants were sealed under a vacuum in quartz ampoules and heated for not less than 100 hours at 1050°C. The lattice parameter a0 of the cubic bronzes was determined from Debye-Scherrer X-ray powder patterns. The cerium content of the bronzes x was established by isotopic dilution techniques. Cerium tungsten bronzes of cubic symmetry were found to crystallize in the range 0.070 < x < 0.186. The lattice parameter a0 was found to increase linearly with x in the cubic range according to the relationship a0 = 0.2165x + 3.8008.
